I read Getting Things Done and created a GTD-system using Evernote and Google Calendar on my iPhone and computer. But, I've found this combination to be somewhat inefficient and hard to use.
A few friends of mine have recommended trying Appigo To-Do, Remember the Milk, and Google Calendar on my phone and computer. Have any of you attempted something similar?
Do you use/recommend a different combination of applications for an iPhone/desktop GTD system?
